I never waste my time trying to "charm" or "impress" a potential date. IMO, I'd rather be hated for what I am then loved for what I am not or for some fake front I put up to appear more "date worthy".
Dumb question... It's like asking what is funny and how do I be funny. If you think some tricks of getting a girl to do what you want is something good, you don't deserve to know how to be charming anyway.
